     * 自定义线程
     * @author yanhaijiang
     * 核心线程数10：线程池创建时候初始化的线程数
     * 最大线程数20：线程池最大的线程数，只有在缓冲队列满了之后才会申请超过核心线程数的线程
     * 缓冲队列200：用来缓冲执行任务的队列
     * 允许线程的空闲时间60秒：当超过了核心线程出之外的线程在空闲时间到达之后会被销毁
     * 线程池名的前缀：设置好了之后可以方便我们定位处理任务所在的线程池
     * 线程池对拒绝任务的处理策略：这里采用了CallerRunsPolicy策略，当线程池没有处理能力的时候，
     * 该策略会直接在 execute 方法的调用线程中运行被拒绝的任务；如果执行程序已关闭，则会丢弃该任务
